For a 27" monitor I'd want to go higher resolution than 1920x1080, otherwise it'll look a bit pixelated.
2560x1440 is the next step up and they start around £220.
From there you want to narrow it down based on the stand and the connections.
If you want a 4k monitor (3840x2160) you'll be looking at ~£300 although there are some a bit cheaper: https://www.scan.co.uk/shop/computer-hardware/monitors/4k-monitors
